NEED ADVICE - Portal thoughts

Portal, Affliate sites, sub pages

korelian

I am working on a Regional PORTAL that will have basically every business under the sun in that region that would like to be included...

I am going to sign them up at their business, and I need to be able to create a subdomain for them and it be a 1 page website, kind of like when you click on the details page of a Portal Directory you get the details of that advertiser.. well it needs to be a 1 page website generated when I ad them.. does anyone know of a portal, or CMS or script that is already made for this? or something CLOSE?

If I don't make myself clear please let me know what isn't clear and I will try to clarify!
